To cllfwhcfri 'L13 may concer/n.:

Be it known' tlnit l, jini-min PsLLn'rrnn, s citiiaen ci' the United States, residing;r :it Chicago, county ot' Cook, and Stilte oi lilinois, ive invented certain new und useful Improvements in Meeus for Generating Powe-r, of which 'the following is s specifi cation.

My inventioii relates to improved .means for generating power and has for its objecttlie production of such means which shell be especially adapted to the utilization of ctmrpressed sir als s motive timid ind 'which snail be economics-ii in operation.

My invention consists in the conibineeion ond errsngenient of ports hereinafter clescribed .Q Q claimed.

My inreiiiion will be best understood by reference to v the accompanying drm/ings form-ing s sert of this speciiicetion, sind in which,

Figure4 is s side elevation of the primary com ressed sir engine employed in my apparotns, 2, e vertical section oorrespending to Fig. L Fig 3, e yerticoi 'section of the secondary corniiresset sir engine, QF it, e. iop pien view iilristreting both prniniry incl secondary engines and their connections, rfig. 5, e side elevation of ating the sanne, Fig. 6, a section on line tiene' ci l, Fig. 7, sn, enlarged clevertion of the automatic governor, and 8, e sect-ion iiliistreting the cani `tor operating the exhaust' relire, l

In the preferred form ot' construction for carrying my invention into eieet, i provide e Iprinniry compressed. sir engine l. En gine l comprises receiving' cylinder 2 in which reeiproczites :i piston 3 connected by ineens of s hollow piston rod with u second piston 5 reciprocating in s beating cyiinder S 'in axis/. tilineinent with cylinder Pistons and 5 are provided with central passige 8wiiicb in conjunction with ton rod el, serv sto torni s continuons open passare between the operetiveportions or" cylin ters E?, snai A clieclr voire 5% serves to permit the passage of compressed sir, or other, uid from the operative enti of cylinder 2 to she operative end of cylinder G but to f rerent passage iliereof in the opposite reetion. Projecting from the operative rece of pistoii is s, tubular inember i0, co .thev in the operative enti of cylinder 2 is a peti 11 preferably of rubber and provided with central opening l2 adapted to receive and tightly tit the tubular member 10. connecting pipe 1 3 communicates with cylinder 6 through :t check i'slrc le slightly above the bottom of said cylinder, and serres to connectsuid cylinder with the cooling Acoils l5 inclosefl in clniniber 16, to which a cooling medium muy be sclniitte and withdrawn. through pipes 17. By this :i1-rangement `it will be seen that upon descentof piston. 2 :i snisii quantity of air or tber i'ind will be imprisoned between the sce of seid piston and. the rubber plate 11 to serre s cushion to check the down- Wertl movement of seid piston. l

Links i8 serve 'to connect piston S with s. bii'lncstetl rocker erin l) iin-ed to a rocker shaft. 2O rotatably mounted in the casing of cylinder 2. it its outer enel shaft 2O carries s crank anni rotatably mounted thereon anti pirotccl to e iizilt bar 2&2. Crank arm 21 carries zi clutch member 9.3 adapted to engage s, clutch ineinber 2i which is splined to shaft 20, i lisntlie lever .25 pivoted to a lng QS extenfing from the wall of cylinder 2 serves :is s means for throwing clutch 24; into engagement with clutch 23 .to place the shaft 20 finder the domination of link bar llink 22 is Vprovided. 'with an elongated slot 2i" engaging over Aoower shaft 28 :incl carries a. roller 29 contacting with :i cani ixmirto slnift 28, iiziicl nin comprises :i cylindrical portion l0 anni s inngedportion 3l adapted to swing rzuiiailiy sint serve als s continuation of portion Un tiic hub 32 of smid cuni member is loosely mounted an eccentric 33 carrying astral) Bei connected by nicuns of the bar-35 with portion 31 of seid com. Centrifugal weights 3G are pivotccl to the rim .of scid cani member by means of arms 37 which arc in turn conncctecl witiol eccentric 33 by means of links 38. Springs 39 tenti to draw wcifrhts 36 inwsmily toward elio center of sliut 28. B

thisarrangement it will be seen that ss'sha t 28 rotates in the direction indicated bythe arrows in Fig'. l the link bar E29 will be caused to reciprocate and, when clutch 24: is in engagement with clutch 23, cause rockingr of slist f2() und consequent reciprocations o laissons 3 :intl 5. it each reciorocntion of simi pistons charge of sir w11 be drawn into cylinffier 2 and transferred to heating cylinder 6 through the agency of check valves 9 and 14. Upon increase of speed of rotation of shaft 28 the weights 36 will be caused to move outwardly under the influence of the centrifugal force as indi cated by the arrows in Fig. 7. This outward movement of weights 36 will rotate eccentric 33 on hub 32 thus drawing hinged portion 31 inwardly toward the center of rotation. This diminishes the movement of link 22- and consequently the movement of pistons 3 and 5 thus diminishing the charge of air drawn into cylinders 2 and 6 and so constituting an automatic governor for the engme. v

In order to facilitate the heating of the compressed air or other fluid in cylinder 6, the iston -5 is provided with a conical ex-l tension or end 40 having lateral perfora tions 41 for escape of air from passage 8. Cylinder 6 has a conically extending head 42 adapted to accommodate extension 40. -J a cketing chambers 43 are provided around cylinder 6V and extension 42 for the purpose of. communicating heat 'to the interior of said cylinder and extension. Cylinder 6 is in open communication'with power cylinder 44 through the medium of passage 45. A power piston 46 is mounted in cylinder 44 and connected by means of a connecting rod 47 with crank arm 48 on power shaft 28. A check valve 48 is preferably provided for the crank case in order to produce a pressure therein. Jacketing chambers 43 are extended to encompass cylinder 44 so as to communicate heat to the interior thereof. An exhaust valve 49 carried by a Valve stem 50 having a grooved collar 5l, is held to its seat by means of sprin 52. Collar 51 is connected with a valve Iev'er 53 fulcrumed in a standard 54 and connected with a valve rod 55 carrying a roller 56 coperating with a cam 57 on power shaft 28, to exhaust Acylinder 44 at the proper time. Exhaust valve 49 ,communicates with an exhaust pipe 58 connected with cooling coils 15. By this arrangement it will be seen that compressed air or other fluid introduced into the cylin- Ider 6 will be caused to expand by the heat from j acketing chamber 43 thus causing pis: t0n 46 to reciprocate and drive power shaft 28 with the results as above described. The exhaust from cylinder 44 passing through cooling coils 15 is returned to receiving chamber 2 and is thus used continuously.

In order to provide a heating medium for the jacketing chamber 43 I provide coils 59 connected by pipes 60 and 61 with said jacketing chamber. Coils 59 are preferably inclosed in a suitable casing with' engine 1 and exposed to the action of the sun by means of glass plates 62 placed thereover. By this arrangement it will be seen that .water or other fluid in coils 59 will be heated by the action of the sun and caused te .circulate through jacketing chamber 43 thus impartin heat to the compressed air or other fluid in the engine and causing the operation thereof. v

In order to render the en 'ne operative at night or when the heat of the sun is not available or sufficient I provide additional conn'ecting pipes 61 and v63 for jacketin chamber 43, the said pipes being connecte with a boiler 64, whereby live steam may be circulated through jacketing chamber 43. Suitable'valves are provided in the pipes for making this change and a drain pipe 65 having a valve 66 is provided for draining jacketing chamber 43 preparatory to usinor steam' as the heating medium. A valve 67 serves to admit air to jacketing chamber 43 to assist in the draining thereof.

In conjunction with the engine above described I employ a-secondary engine precisely the same in all details of construction and plan of operation except that the circulating pipe connections are different. Such an engine is illustrated in Fig. 3. When the sun coils 59 are utilized for supplying heat to engine 1, the same source of heat is employed for supplying heat to the secondary engine. For this purpose a connertion is made between jacketing chamber 43 and said sun coils by means of the pipe 68. A pipe 69 also serves to connect said sun coils with a pump .70 in turn connected by means of pipes 71, 72 and 73 with jacketing chamber 43. By this means it will be seen that a circulation of heated water or other fluid from sun coils 59 may be maintained in jacketing chamber 43 of the secondary engine. Either of the engines may be started or stopped bymanipulating clutchhandle 25. In starting the engines, however, it will generally be found preferable to lirst shift clutch 24 into engagement for only a partial stroke of piston 3. By the time the power shaft 28 has taken one full rotationV the automatic governing eli'ect of the weights 36 will become edective and the clutch may be finally shifted into engagement. Then fuel heat from the boiler 64 is employed as the means for supplying heat to the primary engine, I employ the exhaust from said primary engine as the means for supplying heat to the secondary engine thus utilizing heat units which would otherwise be wasted. To this end I connect pipes 74 and 74 with exhaust pipe 58 on o posite sides of the valve 75 therein. Iipes I74 and 74 are connected with jacketing chamber 43 of said secondary engine as indicated in Fig. 3. By closing valve 75 it will be seen that the exhaust from the primary engine will be caused to circulate through the jacketin chamber of thesecondary engine imparting its heat thereto, and then returns to the coolin coils ofthe primary engine to be again used as the motive fluid for said priinnry engine. Suitable nic-cnc :suoli ns nui- 76 and 7i niey be emplcyei for utilizing the power from primary and Sec onclecy engines, and ii"- fiesireii the pump '(0 may be dircclly connected with lie sha-ft 28 ci the scconclory engine exienciccl. lVlien lie' sun coils :irc employed is lelie means for supplying licei; to ooili engines prefer 'io nec compressed nir of liign com pression in iio'ilr of Said engines, bui when the boiler is cocci as the source of lient for ine prininry engine l prcfcr cf-3c comprcssecl n; ilic motive llnicl ilicrein lim ing a nincli lower pressure. licei instance ll pr ier in use. compressed 'inving c precsnre oi one thousand por per sonore incn in bolli nee; @ncl i ille inticr ineicncc @Liefer lo nee compressed en.' in lilo a pres sure of nloolii two lonnclred pcnnfls pci sonore inci,
